Security system, security method and recording medium storing security program

Abstract

A security system to give a user in a specific area use authority based on authentication, and to permit use of the specific area by the use authority. The security system includes an authentication unit to authenticate a user, a position detection unit to detect at least one of a position and move of a user, and a use authority control unit to monitor at least one of a position and move of a user to whom the use authority is given based on the authentication of the authentication unit by a detection output of the position detection unit, and, if a distance between users is equal to or below a predetermined value, to change the use authority which is given to each user.

1 . A security system to give a user in a specific area use authority based on authentication, and to permit use of the specific area by the use authority, the security system comprising:
 an authentication unit to authenticate a user;   a position detection unit to detect at least one of a position and a move of a user; and   a use authority control unit to monitor at least one of a position and a move of a user to whom the use authority is given based on the authentication of the authentication unit by a detection output of the position detection unit, and, if a distance between users is equal to or below a predetermined value, to change the use authority which is given to each user.   
     
     
         2 . The security system of  claim 1 , wherein
 the use authority control unit sets use authority of the same or a different level to users based on the authentication, and, if a distance between the users is equal to or below a predetermined value, the use authority which is set for each user is changed to use authority of the lowest level.   
     
     
         3 . The security system of  claim 1 , further comprising:
 a user trace unit to trace an authenticated user, wherein the use authority control unit maintains the use authority or changed use authority of the user based on tracing of the user tracing unit.   
     
     
         4 . The security system of  claim 1 , wherein
 the use authority control unit sets the use authority for every service, and, if a distance between users is equal to or below a predetermined value, the use authority which is set for each user is changed into use authority which is calculated from a logical conjunction with service.   
     
     
         5 . The security system of  claim 1 , wherein
 the use authority control unit lowers or cancels the use authority of each user if a distance between users is equal to or below a predetermined value.   
     
     
         6 . The security system of  claim 1 , wherein
 the use authority control unit does not give the use authority to the authenticated user if it is detected that a distance between the authenticated user and another user is equal to or below a predetermined value.   
     
     
         7 . A security method to give a user in a specific area use authority based on authentication, and to permit use of the specific area by the use authority, the security method comprising:
 authenticating a user;   detecting at least one of a position and a move of a user; and   monitoring at least one of a position and a move of a user to whom the use authority is given based on the authentication, and, if a distance between users is equal to or below a predetermined value, changing the use authority which is given to each user.   
     
     
         8 . The security method of  claim 7 , further comprising
 setting use authority of the same or a different level to users based on the authentication, and, if a distance between the users is equal to or below a predetermined value, changing the use authority which is set for each user to use authority of the lower level.   
     
     
         9 . The security method of  claim 7 , further comprising
 maintaining the use authority or changed use authority of the user based on tracing information of the authenticated user.   
     
     
         10 . The security method of  claim 7 , further comprising
 setting the use authority for every service, and, if a distance between users is equal to or below a predetermined value, changing the use authority which is set for each user into use authority which is calculated from a logical conjunction with service.   
     
     
         11 . The security method of  claim 7 , further comprising
 lowering or canceling the use authority of each user if a distance between users is equal to or below a predetermined value.   
     
     
         12 . The security method of  claim 7 , further comprising
 not giving the use authority to the authenticated user if it is detected that a distance between the authenticated user and another user is equal to or below a predetermined value.   
     
     
         13 . The security method of  claim 7 , further comprising
 notifying that the use authority is not given when authenticated if it is detected that a distance between the authenticated user and another user is equal to or below a predetermined value.   
     
     
         14 . A computer-readable recording medium storing a security program that includes a function to give a user in a specific area use authority based on authentication, and to permit use of the specific area by the use authority, and that causes a computer to execute the function, the program comprising:
 authenticating a user;   taking in detection information representing at least one of a position and a move of a user; and   monitoring at least one of a position and a move of a user to whom the use authority is given based on the authentication by the detection information, and, if a distance between users is equal to or below a predetermined value, changing the use authority which is given to each user.   
     
     
         15 . The recording medium of  claim 14 , the program further comprising
 setting use authority of the same or a different level to users based on the authentication, and, if a distance between the users is equal to or below a predetermined value, changing the use authority which is set for each user to use authority of the lower level.   
     
     
         16 . The recording medium of  claim 14 , the program further comprising
 maintaining the use authority or changed use authority of the user based on tracing information of the authenticated user.   
     
     
         17 . The recording medium of  claim 14 , the program further comprising
 setting the use authority for every service, and, if a distance between users is equal to or below a predetermined value, changing the use authority which is set for each user into use authority which is calculated from a logical conjunction with service.   
     
     
         18 . The recording medium of  claim 14 , the program further comprising
 lowering or canceling the use authority of each user if a distance between users is equal to or below a predetermined value.   
     
     
         19 . The recording medium of  claim 14 , the program further comprising
 not giving the use authority to the authenticated user if it is detected that a distance between the authenticated user and another user is equal to or below a predetermined value.   
     
     
         20 . The recording medium of  claim 14 , the program further comprising
 notifying that the use authority is not given when authenticated if it is detected that a distance between the authenticated user and another user is equal to or below a predetermined value.
